Planning their attack carefully, the mercenaries split into two teams; the fist team ambushed Queen Amidala and her security captain, Quarsh Panaka, who were to reunite with Senator Palpatine at the Senate Building. Captain Panaka successfully defended the queen, although she was briefly captured by the mercenaries and assailed by hover cannons. Panaka liberated her from her temporary prison in the undercity and prepared to return to the surface with her. However, the Sun Guardleader of these mercenaries, who wore a black hooded warrior's uniform and was armed with a vibro-ax, confronted the queen as she was about to leave the Underworld. Captain Panaka skillfully fought this final assassin and killed him with his R-65 heavy blaster.[1]

All of the mercenaries used various lethal methods including a range of hand-to-hand and pistol combat. Others utilized thermal detonators and most of the assassins were killed by the Jedi's lightsabers or by Captain Panaka's variety of blasters.[1]
